Generally, you can cancel a car contract in Texas without penalty in the following circumstances: If you have not taken delivery of the car. If the car is defective. If the dealer misrepresented the car.
A debt cancellation agreement (DCA) is an agreement that the holder of a retail installment contract will cancel a specified amount owed on the contract if the vehicle is stolen or totaled. Some DCAs require that the retail buyer maintain insurance on the vehicle.
Chapter 354 debt cancellation agreements apply only to retail installment contracts, not loans or leases. Debt cancellation agreements for consumer loans are subject to a different provision: Section 342.4021 of the Finance Code.
In short, debt cancellation agreements (sometimes referred to as “Gap”) are contracts that cover the difference - or the gap - between what your new vehicle is actually worth and the amount you still owe on it.
